When a guy says he wants to take it slow?

We’ve been talking and hanging out for about a month and a half now, very casual and just having fun
We talked and he said he wants to take this slow before we get serious, he has goals of buying a house and car so he’s been working full time

Do guys say this to girls they aren’t serious about or to girls they can see a LTR with?
